supplies
CAUTION:
Make sure the AC power supply uses a three-wire cable with a protection wire, and the PE wire of
the AC power supply is correctly grounded at the power distribution room or AC power supply
transformer side. In addition, make sure the PE terminal on the router is correctly connected to the
PE wire of the AC power supply.
If the router is AC powered and no grounding strip is available at the installation site, you can ground
the router through the PE wire of the AC power supply, as shown in
Figure3-5 .
